I work part time in sales.
Every fucking morning our manager gives us all a team bollocking and it's really getting on my nerves. Nothing we ever do is good enough. If we hit our targets then they just increase the target for us for the week so we never hit it!
I have always worked in sales environments so I know that sales are pressured, but I don't know why on earth any boss would think that it's going to motivate staff if they tell them off constantly. We are also pulled into the office in turns throughout the day very frequently and bollocked then too!
